Taking trouble to point out (8)
I believe the answer is:
adoption
'taking' is the definition.
(thesaurus)
'trouble to point out' is the wordplay.
'trouble' becomes 'ado' (I've seen this before).
'to' says to put letters next to each other.
'out' indicates an anagram (out can mean wrong or inaccurate).
'point' is an anagram of 'ption'.
'ado'+'ption'='ADOPTION'
(Other definitions for adoption that I've seen before include "formal selection of candidate?" , "The taking on of someone else's child" , "ratification" , "approval" , "fostered" .)
